l Claim.

fa collapsible tripod mounting means which gives secure support to a gun or the like when in raised position, and which can be collapsed to a position in which it occupies little space.

A urther object of the invention is' to provide a mount of this type which can be collapsed without the removal of the gun therefrom, so that it may be easily and quickly installed in an oper.

- vIniiversally movable relation to permit manipulation and aiming thereof.

Still a further object of the invention is, to provide a mount of this type with a simple means for removing the gunftherefrom.

strut having legs t connected by pivots 8 to projections Ill from the iloor d. l.At its upper end the V-shaped member has an enlarged tubular portion I2 provided withl a projection It on the rear side. This projection carries a pivot I6 on which is engaged one end of a link I8 which exv tend downwardly and rearwardly. The lower end '20 of link or strut I8 is formed to engage within a U-shaped frame 22 secured to a fixed part 24 of the structure. The legs of the U- shaped portion 22 and of the end 2|! are provided with holes which can be brought into registration, so that a pin 26 having a handle 28 can be inserted therethrough. Thus the link I8 may be heldin a. position to support the V-shaped main frame member.

The gun 2 is pivoted to turn about a vertical axis on pins 30 mounted in the ends of a U- shaped member 32. The bight 3l!` of this U- shaped member is pierced by a headed block 36 ,(Fig. 3), thus forming a pivot for the frame 32 about a vertical axis. f

Block 36 extends into the end of tubular portubular section I2. `A sleeve 44 is mounted to An additional object of the invention is to provide a. mount of this type which holds thev gun Dart thereof.

In the drawings:

Fig. 1 is a side elevation of a gun mount embodying my invention; 9

Fig. 2 Is a front view thereof; i

Fig. 3 is an enlarged detail principally in lsection through the swivel joint and connection between the gun and the mount;

F154 is a cross section on the line I-l of Fig. 3; and j Fig. 5 is a viewsimilar to Fig. 4 with the parts in released position.

As shown in the drawings, the gun indicated generally at 2 is to be mounted preferably within a compartment having a iloor indicated at I.

turn on the outside of the tubular section I2, being prevented from slipping od the end thereof .by an inwardly turned flange 46 engaging in a groove in section I2. The lsleeve 44 has cam shaped grooves 4B of gradually increasing depth opposite the balls 40.

When the parts are in the position shown `in Fig. 5. the balls 40 are able to move into the deeper ends of grooves 48 and thus out of the 'grooves 33 in the block 36. Thus the block may beremoved with the U-shaped member. 0n the other hand, if sleeve 4I is turned to the position shown in Fig. 4 the shallow parts of the grooves 48 force the balls into groove 28 and thus lock the block 35 to the V-shaped frame.

Likewise pivoted on the pin I6 is a lever arm 50 having at its end a jaw 52 provided with a partly circular recess. Pivoted at 54 on lever '50 is a cooperating lever having a handle portion- 56 on one side of the pivot and a jaw portion i8 provided with a partly circular recess cooperating with the recess in the jaw portion 52. -A flatleaf spring 60 rests against lever 50 on one side of the pivot 5l and against the back of :law portion 58, thus urging .law portion 58 towards Jaw portion 52. The gun is provided with a. pin 82 adapted to be enclosed between The gun mount includes a V-shaped member or jaw portions $2 and is.

When the parts are in the position shown in solid lines in Fig. l, the gun is in a raised but stowed position. Because of the engagement of lever 50 with pin 62, the gun is incapable of moving and is therefore held stationary.

If the gun is to be operated, lever 56 is pushed towards lever 50 so as to move Jaw 58 and release the pin 62. Lever Si) is then dropped to the broken line position shown in Fig. 1.

` Inthis position the gun is left free to turn about axis 30 and swivel block 36, so as to have a. universal movement.

In order to collapse the whole mount, pin 26 is removed. The V-shaped frame 6 may then swing downwardly to the position shown in broken lines in Fig. 1 and in such position the lever I8 collapses between the legs of the V- shaped member. The gun also can lie substantially fiat on the floor llin such collapsed position.

While I have described herein one embodiment of my invention, I wish it to be understood that I do not intend to limit myself thereby except within the scope of the appended claim.

I claim:

In combination with a supporting structure, a gun mount of tripod form comprising an inverted V-shaped strut and a single rigid strut, pivotal means on the apex of said V-shaped strut constructed and arranged to support a gun, pivots connecting the ends of the legs of said V-shaped strut to said supporting structure for collapsing movementthereagainst, an additional pivot connecting one end of said single strut to the apex portion of said V-shaped strut for pivotal movement about an axis parallel to the pivotal axis of the V-shaped strut, lever means having a common pivot with the single strut for locking the gun against movement on the mount, and a readily removable pin extending through the Othelend of said single strut and into a portion of the supporting structure for maintaining the gun mount rigidly in its uncollapsed tripod form.
